He was 19 at the time he wrote that. He is 33 now. I'm not sure it's natural or fair to judge someone predominantly on an off-the-cuff comment they made almost half their lives ago. I certainly said things at 19 that I wouldn't want attached to my professional identity and that aren't representative of my beliefs and mindset now. While I don't know you, the same is likely true of you, or will be someday.

How long in the past does something like that need to be before you can start taking other evidence into account?
